On Friday, House Minority Leader Kevin McCarthy, R-Calif., urged Democratic leadership to admonish Omar and Tlaib due to their backing for the BDS movement, which is meant to put economic pressure on Israel to end its occupation of the West Bank.

McCarthy, in an interview with Breitbart News Saturday, accused Democrats of double standards for refusing to punish Omar and other lawmakers for anti-Semitism, while pushing for the censuring of Rep. Steve King (R-IA) for his remarks about white supremacy.

Conway's reaction is the first from the White House after Omar's tweets, which have been widely panned by Republican and Democrat's alike.

The Representative for Minnesota, Ilhan Omar, retweeted a post Sunday implying that she believed the Israel lobby, the American Israel Public Affairs Committee (AIPAC), was paying American politicians to hold pro-Israel positions.

He wrote that he's "one of those American Jews who opposes the occupation, laments Israel's anti-democratic drift, and doesn't regard the country as especially central to my Jewish identity". Josh Gottheimer and Elaine Luria write in a draft letter obtained by The Washington Post.

"It's clear that congresswoman Ilhan Omar harbors deep-seated anti-Semitic views", Carnahan said in a statement. "They do not belong in any conversation, period".

"The AJC tweeted at the congresswoman, "@IlhanMN, Suggesting that a Jewish organization is buying off American politicians is both demonstrably false and stunningly anti-Semitic.

Omar's unusually outspoken criticism of the pro-Israel lobby has rattled some of her Democratic colleagues.

The first anti-Semitic trope Ungar-Sargon referred to was when Omar said in 2012 that "Israel has hypnotized the world".

"We are deeply alarmed by recent rhetoric from certain members within our caucus, including just last night, that has disparaged us and called into question our loyalty to our nation", they wrote in the letter.

"We should expect all elected officials, regardless of party, and all public figures to not traffic in anti-Semitism", she said.

Kildee was asked to explain Omar's suggestion that Republicans who criticize her rhetoric have been bought by "Jewish money". "I look forward to building an inclusive movement for justice with you".
